Dynamics and Control of a Fully Heat-Integrated Complex Distillation Column

Distillation is the most widely used in the separation section of a process. It consumes an important amount of energy (close to 40 % of the energy of chemical process). Many different configurations to increase its thermodynamic efficiency have been proposed. In this paper a new distillation column configuration developed by Toyo Engineering Corporation called SuperHIDiC is analysed. This new column is simulated and compared with a conventional distillation column. Its dynamic performance and control structure performance are also analysed. Results show that SuperHIDiC achieves an important reduction in energy consumption and that a conventional control configuration can be used in order to have a stable operation.
